Study Notes

A system is a group of parts that work together to perform specific functions.
The human body has ten different systems that work together to keep us healthy and functional.

The nervous system consists of the brain, spinal cord, and nerves.
The brain is the control center of the body, sending signals through the spinal cord to nerves all around the body.
Nerves are cables that help move signals around to different parts of the body, controlling functions like breathing and blinking.

The respiratory system provides the body with oxygen through breathing.
Air enters the nose and mouth, passes through the trachea in the throat, and enters the lungs.
In the lungs, oxygen is transferred to the blood, which is then circulated throughout the body.
Oxygen is essential for powering the body's functions.

The cardiovascular system consists of the heart and blood vessels (tubes that carry blood).
The heart pumps blood throughout the body, delivering oxygen and nutrients and helping to protect against diseases.
Blood vessels carry blood to all parts of the body.

The digestive system breaks down food into nutrients, absorbs them, and eliminates waste.
Major parts of the digestive system include the stomach and intestines.
Nutrients are absorbed from food and circulated throughout the body, providing energy and essential substances.

The musculoskeletal system consists of bones and muscles.
Bones support the body, protect organs, and produce blood cells.
Muscles are connected to bones, receiving messages from the brain through nerves, and facilitating movement by pulling on bones.
The largest muscle in the body is the gluteus maximus, which is used for sitting.
